sodium batteries: the new challenger to lithium-ion for use in electric vehicles - battery energy storage
As the electric vehicle market is about to break out, the European Union plans to launch a battery --
Researchers at Stanford University have set up a consortium to bring the continent to the global electric vehicle battery space, and they have published a paper claiming that their sodium batteries can compete with lithium
Market leader.
In the context of the expected size of the electric vehicle market, the development of new batteries is quite slow, and so far, no innovation has proved as economical as lithium. ion.
Sodium for Stanford batteries
Cheaper and richer material than lithium
It is still in the stage of development.
Sodium forms the cathode of the Stanford battery, and the anode is made of phosphorus, adding a compound called myo -.
O-l alcohol that can be extracted from rice skin or corn.
According to the researchers, the efficiency of this chemical combination is comparable to that of lithium.
Lower cost ion batteries
The cost is much lower.
But there's always an exception.
First of all, even Zhenan Bao, the leader of the Stanford team, said that in terms of performance, lithium-
Never hit an ion battery.
While the sodium battery is cheaper now, its creators haven't figured out how to make it cheaper when they try to match Lithium
Storage capacity of Ion batters.
The main advantage of sodium batteries is that sodium is much richer than lithium, which costs only $150 per ton, while lithium costs only $15,000.
This works with the performance optimization of the researchers, turning their batteries into costs-
Effective alternatives to lithiumion batteries.
However, this may not be enough to ensure that the sodium battery takes off, although the power to find a lithium replacement --
As the world prepares for fossil fuels, the ion mixture is bound to continue --free future.

Ion batteries remain the undisputed leader in battery packs, and may continue to do so for many years to come --
It's not just because of their performance.
This is also because of the cost of lithium.
Ion batteries are falling and, more importantly, a lot of money is being invested in lithium mines and battery factories.
Earlier this month, the vice-chairman of the European Commission said that the EU will become a competitor in Asia and the United States for automation, engineering, and discussion of how Europe joins the battery boom. S. manufacturers.
At present, there is little battery production capacity in Europe.
Batteries are mainly imported from Asia.
However, if European automakers are to keep their promise to expand to electric vehicles, they will need battery capacity.
Volkswagen is one of the most ambitious newcomers in the field of electric vehicles.
The automaker plans to own 23 Volkswagen cars.
By 2025, brand electric cars and 50 electric cars of 12 brands.
In order to achieve these goals, Volkswagen will need four gigabit battery batteries and will seek help from local and international partners.
Bosch, another German company and the world's top auto supplier, may be one of those partners as the company is considering a huge investment in battery production.
Billions of euros of investment is not a decision made by enterprises without considering long-term investment.
Therefore, any such investment will help to strengthen lithium-
Ion batteries has a place in the market.
However, there is hope for an alternative as long as they prove themselves to be a valuable alternative.
CEO of Daimler Corporation
Car manufacturers who canceled their battery production business a few years ago --
I believe that if there is a breakthrough in battery technology, there will be interested parties.
"If we make a breakthrough in our house or elsewhere. . .
This could be a new game where we have the opportunity to build a competitive position, "said Cai.
As a result, automakers who do not have a strong position in battery manufacturing are paying close attention to the new battery technology.
This will certainly stimulate more research on lithium.
Leading technologies may also be encouraged to further reduce costs. Oilprice.
